Nuclear risk is a contained problem. Access is extremely limited and controlled by low tech hardware locks. The technology is understood, we know what makes bombs explode and it is predictable by physics.

AI is the opposite of all these characteristics. Its access is nearly everyone. The technology is not understood and not predictable. It is a nuclear warhead that thinks for which we don't know what might make it explode.

Yes, although I wouldn't go as far as to claim that current AI technology has any sort of "accessible to all" path to AGI. Accessible to irresponsible actors with lots of money? Possibly, and that's the real risk. But at least it's not an absurd comparison unlike the GP's.

Unlimited power makes everyone irresponsible actors. Nvidia already stated they expect a million fold processing power in 10 years for AI.

> Computer proliferation is not an existential risk.

AI is created and run on computers so AGI risk must by definition be a subset of computer proliferation risk
